2022 Jeep Grand Wagoneer Electrical System Problems

I own a 2022 Jeep Grand Wagoneer Series III (VIN [XXX] ) that has experienced repeated, unresolved electrical system failures which pose a direct risk to my safety and to the motoring public. The vehicle has already required fourteen warranty visits, with thirty-one days out of service and twenty repeat repairs. The problems include multiple no-crank/no-start events that have left me stranded, four premature battery failures, and ongoing electrical malfunctions affecting the instrument cluster, infotainment system, HVAC, rear camera, mirrors, power running boards, and other electronic modules. These failures show that the electrical system is unstable and unpredictable. On [XXX], after the latest no-start incident, the dealership’s service manager told me directly that the issue was “more than just a bad battery.” Despite this acknowledgment, the only action taken was to replace the battery for the fourth time and declare the vehicle “repaired.” Jeep’s customer care initially agreed that the history showed a deeper safety issue and promised to open a STAR engineering inspection, but that inspection has never been scheduled. Instead, I am being pressured to pick up and drive a vehicle that the dealership itself admitted has unresolved electrical problems. This is not just a matter of inconvenience — the risk of sudden electrical shutdowns while driving, or the loss of critical safety systems such as brakes, steering modules, and cameras, presents a clear hazard to my family and others on the road. A vehicle with this history should not be returned to service based only on repeated battery swaps while the underlying defect remains unidentified. I respectfully ask NHTSA to investigate the 2022 Jeep Grand Wagoneer Series III for systemic electrical failures and to ensure that Stellantis does not force consumers to operate unsafe vehicles that continue to suffer from recurring electrical shutdowns.

The front passenger seat lumbar/massage system malfunctioned and inflated without user input to maximum capacity. The lumbar air bladder became over-pressurized and created a large, hard, immovable bulge in the center of the seatback. The system will not properly deflate and remains in this condition. The failed component appears to be the lumbar/massage module and valve system, which is electronically controlled. The vehicle is available for inspection upon request. This condition creates a rigid protrusion directly behind the occupant’s spine. In the event of a crash, this would alter occupant positioning, concentrate force on the spine, and interfere with proper restraint function and airbag performance. This will increase the risk of injury to the occupant. The problem has been confirmed by Lander’s Jeep dealership in Little Rock, AR, which acknowledged the issue but advised that diagnosis and repair would be costly and would not be covered under my warranty or extended service contract provided by MOPAR. No warning lights or messages appeared prior to the failure. The issue occurred suddenly during normal use. Online research shows countless similar failures in 2022+ Jeep Grand Wagoneer vehicles, with consistent reports of lumbar/massage module or valve failures causing uncontrolled inflation. Some owners report repeat failures and electrical issues related to the seat module. Given the repeated nature of this failure across multiple vehicles and the potential safety implications, this issue should be investigated as a possible safety defect affecting occupant protection systems. I have multiple more examples of this from Facebook Wagoneer and Grand Wagoneer Owner groups, however I am limited to just 10 uploads.

I was told the vehicle has a TSB out for stuck thermostat in the engine. It can cause malfunctions, overheating, etc. we also have an issue with the trunk door not closing or opening properly due to a module issue.

While driving the vehicle(speed does not matter as this has occurred while standing at a stop light) all safety warning lights illuminate on the dash and render all of my safety features inoperative. This includes: ABS, Forward Collision Avoidance, Rear Collision Avoidance, and Park assist. Once this happens the vehicle becomes extremely difficult to operate and to stop. The remedy is to pull over, turn the vehicle off and open the drivers side door to shut off the RAC (Retained Accessory Control), let the vehicle sit for a minute or two, then restart the vehicle. All light will remain off and the car will function normally. This issue occurs at least 2-3 times per week and is extremely frustrating. I've taken the vehicle to the dealership several times for what they have determined to be a "software issue". Several trips have been for recalls, others have been for this issue and my Infotainment system going black. The Infotainment system going black is the second major issue with this vehicle. The dealership was able to get the system operating again with an additional software update, however it has not completely remedied the problem. The Infotainment system will still black out, but for only a quick second, then it comes back on. When it does this, I loose all settings including profiles and SiriusXM programmed stations. I've done a master reset on the Infotainment system and have had it back to the dealership, but it still has not been 100% resolved. This is a safety risk when it blacks out as I loose navigation, audio, and Bluetooth connectivity. Now my attention is not on the road but on the failed system.

Premature battery depletion. Brand new battery 2 months old was completely dead. On 3rd battery in one calendar year. Stranded with young children in car that cannot even be jumpstarted. Dealer has confirmed issue and has reportedly has had numerous owners with the same issue, same vehicle. No warnings, or prior issue, car has absolutely no power.

Driving the car on the road the car stalled went off and I could not turn it on at all. It has to be towed to the dealership. Luckily, we avoided an accident

December 24-23 was in red lobster to pickup food about 5 mins my grand wagoneer was on fire

The contact owns a 2022 Jeep Grand Wagoneer. The contact stated that while driving 60 MPH, the instrument cluster, Wi-Fi, A/C, Cruise Control, and Navigation System went blank, and failed to display any information. The contact stated that the vehicle had not lost power. The contact stated that the failure was constant. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the vehicle needed a software update to be completed; however, the dealer stated that the update was not available from the manufacturer. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 20,000.

Lane Keeping Assistance, Lane Departure Warning, and Forward Collision Warning-Not working, it had message to service and exclamation in red

Vehicle has a malfunctioning climate control system due to electrical / software issues. When the climate control a/c is set to manual mode it will have a "ghost" control which will randomly change settings, it changes the set temperature - recirculating mode - a/c on and off - fan speed - fan direction (windshield, face, feet) - and will also apply to the rear passenger control unit. The main and lower front climate control screens will act "crazy" when this "ghost/glitch". is happening and randomly change settings, the driver cannot override it when it is happening until the vehicle is shut off. It is extremely dangerous as this malfunctioning climate control will let the front windshield moisture build up and be impossible to clear off - which leads to a visual obstruction and could result in a crash, it's especially bad for us in the PacNW in the winter when it is dark and always wet, not being able to keep the windshield clear is scary. I've reported the issue date as 12/24/22, but it happens frequently. I have recorded videos of it happening on my iPhone but the file size is too large for here. We are still waiting for parts from Jeep to get this issue fixed, there are multiple reports from other owners on this issue also, why is this vehicle allowed to be sold to the public ? It has so many issues.

AC/HVAC: experienced multiple occasion where the system (front and rear) turns on and quickly varies between settings with no way to override. Engine: when speeds are in excess of 80mph front passenger vent makes excessive noise in line with engine rpm’s “Auto drove” ineffective due to lane departure inop, after service for above incidents Radio is extremely intermittent.

Complaint - The wiring harness in my engine compartment is mounted on the firewall below the cowl. It runs from the driver’s side to the passenger side. On my vehicle, it has a significant drop on the driver's side, almost hitting the master brake cylinder cover. The wiring harness does move significantly on the driver's side. Note-Some kinds of clips are molded onto the wire harness cover. Upon inspection of the wiring harness and cover, there is nothing that I and Service Director could find to attach the wiring harness to the firewall to keep it permanently up and away from the driver-side master cylinder brakes. Notes - My vehicle is available to you for inspection if warranted. -Dealership Service Mgr Director and Wagoneer customer service were notified and were inspected. I/we also confirmed and noted that other identical vehicles have the same problem. — inspection was performed either on the service lot by Director and myself or in the Dealership Showroom Display vehicle by me. -WCS officially informed me on 7/8/2022 that the Service Director said my vehicle wiring harness was manufactured as designed, and WCS goes by what the Director says. Because I told them (WCS) I was filling a complaint with NHTSA, they will close my case. -As of this date, no problems or failures are noted. Impression- This potential safety hazard could lead to electrical shorts, major components failure, and a possible fire hazard when the vehicle is in motion due to vibration wear, including off-road use.

While I was driving at around 35 miles per hour and tried to stop in a short distance because of the “should I go or not” situation at the traffic light, the whole vehicle was shut off at a blink of an eye. Soon after I noticed it and tried to imitate the incident to make sure I wasn’t mistaken, it happened three time in a row. The incident can only be seen at night time when light from the headlight is visible since it happens so quick. It wasn’t just about headlight. The engine shut off and turned back momentarily as well. Thankfully each event didn’t last longer than a second and there weren’t any vehicles nearby. When I told a CDJR Monrovia service department manager about the incident and said we need to investigate, he was not serious about it. And nothing was inspected upon the request. There were no warning signs prior to the failure.
